DataStax , the company that powers generative AI applications with real-time, scalable data today released its top predictions for 2024 – spoiler alert: generative AI will be at the top of every organization’s list of priorities.

Key Points: 
  • DataStax , the company that powers generative AI applications with real-time, scalable data today released its top predictions for 2024 – spoiler alert: generative AI will be at the top of every organization’s list of priorities.
  • After simmering for years, AI exploded in early 2023 when ChatGPT and DALL-E went viral, spurring a whole industry of startups.
  • If unemployment and stagnation rise in 2024, we will likely see a backlash from workers who worry about AI displacing their jobs.
  • The leading-edge, agile companies that are building with AI will be pumping out new ways to engage with consumers and businesses alike.

Betelgeuse: star is continuing to behave mysteriously – here's what would happen if it exploded

Briefly it became fainter (just about) than Bellatrix, the third brightest star of Orion.

Key Points: 
  • Briefly it became fainter (just about) than Bellatrix, the third brightest star of Orion.
  • For a few days this year, it was the brightest star in Orion – brighter than we have ever seen it.
  • Betelgeuse, the seventh brightest star in the sky (discounting the Sun), is the brightest of the variable stars.
  • Sometimes Betelgeuse becomes nearly as bright as Rigel (the blue fourth brightest star in the constellation), while at other times it is notably fainter.
  • The brightest and rarest among those are the supernovas, formed when an entire star ends its life in a powerful explosion.

Mysterious behaviour

    • A clump of gas in the wind, as large as the star itself, was obscuring half the star.
    • In fact, images of the star showed the southern half of it to be missing.
    • That said, we still don’t know what caused the sudden brightening – it is now 50% brighter than usual.
    • Betelgeuse’s red colour shows it is a red supergiant, meaning it’s already approaching the end of its life.
    • That could point at fast evolution – meaning a supernova may happen sooner rather than later.

Explosion dynamics

    • Following an explosion, we first would detect a rain of massless particles called neutrinos, which would be harmless to us.
    • After one or two weeks it would shine with about the same brightness as the full Moon.
    • A supernova explosion would also create radioactive iron.
    • In fact this substance has been found in Earth’s seabed and on the Moon, believed to have formed in a supernova explosion between 2 and 3 million years ago.

From platypus to parsecs and milliCrab: why do astronomers use such weird units?

These outlandish comparisons are the invention of Jerusalem Post journalist Aaron Reich (who bills himself as “creator of the giraffe metric”), but real astronomers sometimes measure celestial objects with units that are just as strange.

Key Points: 
  • These outlandish comparisons are the invention of Jerusalem Post journalist Aaron Reich (who bills himself as “creator of the giraffe metric”), but real astronomers sometimes measure celestial objects with units that are just as strange.
  • The idea of a planet that’s 85% the mass of Earth seems straightforward.

Why do astronomers use such strange units?

    • Earth’s radius is about 638 million cm, or 7.5 million Astros.
    • That number of Astros is a bit ridiculous, which is why we adjust our unit choice to one that makes more sense.
    • At an even larger scale, consider the star Betelguese: its radius is 83,000 Earths, or 764 times the radius of the Sun.

Heavy stuff

    • If we want to measure how heavy an asteroid is, we could do it with camels – but in space we’re more interested in mass than in weight.
    • Mass is a measure of how much stuff something is made of.
    • On the other hand, Astro’s mass is how much stuff he’s made of – and it’s the same no matter which planet he’s on.

Astronomical units and parsecs

    • The Sun and Earth are 149 million kilometres apart, and we give this distance a name: an astronomical unit (AU).
    • For example, the centre of our very own galaxy, the Milky Way, is about 8,000 parsecs away from Earth, or 1.6 million AU.

Magnitudes

    • In the second century BC, the ancient Greek astronomer Hipparchus looked up at space and gave the brightest stars a value of 1 and the faintest stars a value of 6.
    • Even more confusing than a negative brightness, each single step in magnitude is a 2.512 times difference in brightness.
    • The star Vega has an apparent magnitude of 0, which is two and a bit times brighter than the star Antares with an apparent magnitude of 1.

At last, the milliCrab

    • The light we use to take pictures of your bones is called X-ray light.
    • When astronomers use X-ray light to observe the sky we sometimes measure brightness in “Crabs”.
    • It’s so bright in X-ray light that astronomers have been using it to calibrate their telescopes since the 1970s.

    Survey says: real-time data powers new revenue growth (Graphic: Business Wire)
    According to the report, 78% of all respondents agreed that real-time data is a must-have, not a nice-to have.
  • The report found that real-time data pays off in two important ways: it leads to increased revenue growth and improved developer productivity.
  • For instance, 71% of all respondents said that they can tie their revenue growth directly to real-time data.
  • Kirschner added, "While the benefits of real-time data are widely recognized, survey respondents identified barrierssuch as data complexity, controlling data costs, and data accessibilityto leveraging real-time data.

This means that all stars in a cluster are born at the same time from the same material.

Key Points: 
  • This means that all stars in a cluster are born at the same time from the same material.
  • Since each prenatal cloud will contain a different amount of material, each star will be born with a different mass.
  • Those with lower masses, similar to our Sun, will live far longer, slowly using their fuel for hundreds of millions of years.
  • However, new data from NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) has revealed a complicated evolutionary past for Westerlund 1.
